SIGNAL LAMP.v

Appiicatiqn flied Maren a, i925. ,seriai- No. 12,431.

Aof the character specied in which theA parts thereofmay be readilyassembled for use, or separated for inspection or repairs, and in whichsaid parts may be readily 'positioned so that a given light may bedisplayed along theV line.

Further, said invention has'for its object to provide a lamp ofthe'character specified in which the several parts thereof are soconstructed and arranged that wh'enthe same are united they will form awind and weatherproof structure.v

Further, said to provide a lamp of the charac-ter specied consistingessentially of a lantern body and a base and having a supporting bracketper manently connected to the base member upon which the lantern body isrotatably disposed so that the same may be adjusted to any one. of alight. l l

Further, said invention has for fits object lto provide a lamp ofthecharacter specified which consists of two enclosing parts havingportions adapted to interengage -to maintain the parts againstseparationrwhen asseii'ibled,

4and to permit ofthe relative rotation of the Further said linventionhasfor its object to provide a lampjof the character-specified in whichthe base member'may be rigidly supported in position, andthelantern'body rotatably `mounted upon said base vso as to permit of theready and convenient adjustment and securement of the lantern body to aplurality of signal displaying positions and ends my invention consists'in t-he novelA `details of construction, and in the combinainvention hasfor its objectplurality of positions to display a given part be obviousandl tion, connection and arrangement of parts hereinafter more fullyvdescribed and then pointed out in the claims. l

In the accompanying drawing showinganr `illustrative embodiment of theinvention-7' Figure 1 is an elevation of one form 4of lamp' constructedaccording to and embodying my said invention; Y f Fig. 2 is an'elevationthereof partly in section; j y

Fig. Sis an elevation thereof with the upper and lower partsthereofshown separated; j Fig. 4: is

y a bottom plan of the upper membeneed Fig. 5 is a top plan of the lowermember. ln said drawings the signal lamp is shown as consistingessentially of a base member 10, and a separate -top member'or lanternbody 19Ywhich is revolubly supported upon said base v10.

rlhebase member 10vjis preferably in the form of a relatively shallowcircular receptacle vhaving a raised bottom 10a, and vertical wallterminatingat its upper edge in anv outwardly projectingvledge or rim18;

To support the lamp, asa whole, in position upon a fixed support, thebase member 1Q is provided with a laterally extending arm 16 having anattaching bracket 17 at its outer end. By preference the said arm andbracket `nre formedintegralv with said base memer 10. Y

secured to yand i l y Y '85 The top member or vlantern body 19 is'hollow, and si'ibs'tantially spherical inQform and? provided in itssides `with a' plurality of openings1in-whicli'are secured 'signallightsfor lenses 20, 21, 22,' 23, ofdiiferent colors to meetV therequirements of the railroad orother purpose in connection with whichthe lamp is used. The' number of signallights is uniml portant and maybe varied to meet any given condition.

I The Vopen 'lower vportion of said lantern 4body 19Vterminates in'adepending annular lflange or wall portion 25 adapted tofully receive andenclose the vupper portion 'of the base 10. Thel flange 25 is providediipOiiit-s inner upper edge with aninwardly extending rannular' shoulder26 which is adaptedto rest upon the upper surface of the outwardlyprojecting ledge or rim 18, and' to ride thereon when-said lantern bodyis rotated relatively to said base'. The ledge or rim 18 also serves asa spacing member to maintain the-wall portions of the parts 10 and 19separated in concentrically spaced relation. Vhen the parts 10, 19 areduly assembled the line of jointure of said parts will be well within,and be protected by the depending flange which serves as a rprotectingapron'in rendering the lamp wind and weatherproof.

To hold thebase member 10 and body portion 19 duly connected, and toallow of the rotation of said body portion upon said base member, thedepending flange 25 of the body portion 19 is provided upon its innerside, in spaced relation to the shoulder 26, with inwardly projectinglugs 27, 27 adapted to engage with the underside ofthe ledge` or rim 18of the base member 10. The flange 25 is also provided, intermediate saidlugs 27, 27,

with a similar but smaller `lug 28 which is adapted to be received bythe recess 29 in the ledge or rim 18 ofthe base member 10, and, afterpartial rotation, to engage with the underside of the ledge or rim 18 ofthe base member.- The lugs 27 23 are y preferably formed integral withthe flange 25.

v In order tohold the lantern body 19 to any one adjusted vpositionsubstantially ninety degrees apart, upon the base member 10 to displayany one of the four signal lights, the

'lantern body is provided at its flange 25 with a radially extendingcasing 31 in which is disposed a normally projected spring-pressedplunger for pin 30 having ahead 30a at its outerp'end. The normallyprojected end of said member. 30 is' adapted to engage with any of fourrecesses`32'provided in the wall of said base member 10, directly belowthe ledge or rim 18-thereof. The number of said recesses, in any case,corresponding with the number of signal lenses mounted in the lanternbody'. i

The illuminating medium may be of any type. In the present instance thesamey is shown'as'of the electricallyv operated type,

vand to vthat end the base member 10 is providedwith a-socket -11,'toreceive an electric lamp 12. The current isl supplied byconductors which'pass through a eompressible Ypacking 13a disposed in a stufiing box 13in the bottom of the base member 10. The lamp V12 is controlled by. aswitch actuating member 14 which also passes through said bot-V tom. Y

The manner of operation of the signal lamp -will be largely vobviousfrom the foregoing description. It need merely be noted that to Vadjustthe lantern body y19, to display'any one ofthe signal lenses mountedtherein, the spring-pressed plunger or pin 30 is first drawn outwardlyto release the inner end thereof from its engagement with-the recess 32of the base.v The lantern body may then be rotated upon the base, andwhen-the same is caused-to assume the desired position the inner end ofthe plunger 30 will automatically enter the appropriate recess 32necessary to hold the lantern body to the position required to displaythe desired signal light.

To detach the base member 10 from the lantern body 19 it merely becomesnecessary to lirst release the locking plunger 30, and then rotatethe'lantern body 19 until the lug 28 is brought into register with therecess 29 in the ledge or rim 18 of the'base member, whereupon thelantern body may be tilted and released of its engagement with the base.

It is to be noted particularly that by means of my invention I amenabled to provide a signal lamp consisting of but two `essential partswhich maybe easily and conveniently joined togetheror separated. As aresult of Y.

the construction and arrangement of said parts, the providing the basemember 10 with means rigidly supporting the entire signal lamp permitsof the ready/adjustmentV or rotation of the entire lantern body withre.

spect to said base member when changes in the signal lights are to bemade. f
